You have to keep in mind that with a TMIC that the idea is efficiency... even more so than power. Also, the fact that an aftermarket TM has A LOT more surface area which is one of the ways it helps cool the air.

If you are going close to 350? Hmmm, well honestly I don't know because I myself wasn't going to take the chance, but I don't know if the stock one can move/cool that much air tbh.

The Process west is by most considered to be THE best... Perrin also makes a very good product and is a bit cheaper, but i'm not sure how much better or worse one would be considered. The perrin will do it's job... it might make a little less power, but that would likely be your only issue.. it might make the same and you saved 200.00 or more.

remember that while we all have the same cars (with exception of years or STI or non) they all will not react the same to the same parts. Some cars are factory freaks and will just have/make more power with the same parts... others may throw codes left and right, so you have to be patient sometimes.
